It’s fair to say that “Spamalot” was not on many bingo cards as a musical must-see more than 20 years after its stage debut. The adaptation of the 1975 film “Monty Python and the Holy Grail” does have the cult cache of the British comedy troupe, as well as a clutch of durable one-liners — up to and including passing gas in one’s general direction. Those jokes, along with batch of fun songs and timeless cultural references, do indeed ensure that “Spamalot” works as well now as it’s ever been. And “You Won’t Succeed on Broadway,” like so much of “Spamalot,” salutes Jewish contributions to the theater world in its own line-treading way. “Monty Python’s Spamalot” runs through Saturday, Jan. 31 at the Fisher Theatre, 3011 W. Grand Blvd., Detroit.
